Methods: A prospective study with a 3-month follow-up was conducted. A total of 62 patients were divided into two groups according to the type of lens implanted: 31 patients with the Liberty lens (61.1 ± 6.4 years) and 31 patients with the Finevision lens (61.9 ± 6.8 years). Three measurement sessions were conducted (baseline, 1 month, and 3 months). These sessions included measurements of the subjective refraction, visual acuity, and defocus curve. Both eyes of each patient were operated on and included in the statistical analysis. Results: Three months after surgery, monocular visual acuity with the Liberty lens was statistically greater than with the Finevision lens at defocus values of -2.00 D (50 cm) and -2.50 D (40 cm) (p < 0.01). In this regard, the near visual acuity results (40-50 cm) with the Liberty lens showed greater variability compared to those of the Finevision lens. Binocularly, however, the Finevision lens demonstrated a statistically significant improvement in visual acuity than the Liberty lens at a defocus of -1.50 D (67 cm) (p = 0.01). Both IOLs provided visual acuities better than 0.20 logMAR for a defocus range from distance (0.00 D) to near (-3.50 D). Conclusions: Future studies are needed to investigate which patient ocular parameters could predict improved near vision with the Liberty lens or intermediate vision with the Finevision lens.
